What Is The Appropriate Chord Size For My Project?
What is the appropriate size of the bottom chord & top chord (timber) for a span of 5.2 meters ( dist.between supports). thank you so much.
We would need a lot more information to be able to offer a guess. Design Criteria typically includes live and dead load (snow + wind + self weight) plus any additional loads like mechanicals or floors hanging from the trusses. We also need to know the distance between the trusses (tributary).
Having said that, 5.3 meters is pretty short, so the members would not have to be very big.
